relevant extracts from glxinfo

I installed Unity 2017.2.0f3 (64-bit) from
https://store.unity.com/download?ref=personal
(click on Windows option)
This gets
UnityDownloadAssistant-2017.2.0f3.exe

Note:
Run winecfg and set Applications->Windows Version to Windows 7. (Otherwise
UnityDownloadAssistant will not run.)
Make sure winbind is installed on your system, otherwise Unity3D does not get
as far as the error reported here.

I ran UnityDownloadAssistant-2017.2.0f3.exe
Some components did not install, but the main installation completed and
claimed to be succesful.

I ran
env WINEPREFIX="/home/bob/.wine" wine C:\windows\command\start.exe /Unix
/home/bob/.wine/dosdevices/c:/users/Public/Start\ Menu/Programs/Unity\
2017.2.0f3\ (64-bit)/Unity.lnk &> unitylog.txt

This displays a window headed "Unity 2017.2.0f3". The contents of the window
are black. After a few seconds, the contents turn to grey. The program takes
100% of cpu and does not terminate.
The software outputs a large number of fixme messages plus the error message 
005b:err:wgl:X11DRV_wglCreateContextAttribsARB Context creation failed (error
1)
